PRAL: potential renal acid load; NEAP, net endogenous acid production; DAL: dietary acid load
*calculated by logistic regression
a unadjusted model
Model I: adjusted for energy
Model II: adjusted for energy, age, socioeconomic status, physical activity, supplement intake, marital status, BMI, dietary fiber, omega3, smoking status, sex, education, and caffeine
